'T 0 all whom'it may concern Be it k-no wn that I, FREDERICK E. PERNoT,

a citizen of the United 'Statesgresidingat- Berkeley, ;in -the county of Alameda and State ;of Ca1iifornia, liave invented certain nals, for Vessels', of \vhich the following is a specification. T p

The present'invention relates to 'improvements-in interinittently operated audible c fog signals, and the-invention'has for its principal: objects to provide an intermittently' operated's'ignal' ivitlfa sound deflecting or directing" mechanisin ivhich .Will -direct the sound issuing from the sounding device 1 in 'difl ere'nt directions, 7 the variation in volume, owing to thechan in direction of projection of the sound, "Warning-an preaching or 'passingvessels oi'the position of thesignal relative thereto,'and When employed on vessels Warning approaching or passing vessels the position and direction of movement of each other.

The invention consists in a suitable inter mittently operated sounding device and a deflector or director associated therewith, Which is'adapted'as the sounding device is operated to-be rotated ona horizontal axis and deflect or direct the sound from one direction to another; and after the sounding device ceases to operate toreturn to its normal; position.

YVith the above "mentioned and other objects in view the invention consists'in the novel construction and combination of partshereinafter described, illustratedin the accompanyingjdraivi'ngs, and pointed out in the:cl ai ms hereto appended;-itbeing understood that'various changes in-"the formyproportion, size and minor details of construction ithin the scop'eof the appended-claims may be resorted-to Without departing from the-spirit or sacrificing any of 5 the: advanig.

tagesof the invention:

To more fully comprehend the invention,

reference is directed .to the accompanying drawings, wherein is'illustrated'a preferred form of invention, and Wlierein Figure' 1 isa view inside elevation ofthe invention, disclosing the mechanism for in termit'tently operating. the sounding device" and" the deflector. Fig. 2*is' a top plan view of the device illustrated in Fig. 1, disclosinggj in dotted lines, the location of the:

sounding; device.

Referring more particularly-to the several views 1 of .thedrawings, wherein 5 like: characters of reference designate, c orre spondingpartsthroughout the, several. views, the numerals. 1 indicate, the side members ofa suitablesupporting frame connect 7 i ed togethen-bysuitable.;-connecting bar s 2.

The-frameis-adapted to bepositioned preferabl-y ensome.elevated portion ofithefship,

Where a comparatively unobstructed passage f inaybe hadbetweeii the bow andstern of the vesselwi p i 1 Rotatablyimoiinted in journals 3, at one,

end of the side z nembers 1, are the tubular a and solid; trunnionsll and 5 of, a suitableljo p21-I2Lb0llC deflector 6, ,andin the curvature]; of said deflector, there ispositioned asuitahle 'g sounding devioe,,and for. purposes of mus ti'atioii I have shown, the same in the form of a Whistle 7 carried Joy a connection Sex} tending through theitubular trunnion 4:, and said connection vis;connect ed at its opposite end to a suitable, source of fluid under pres: sure. Aivalve 9 positioned in thehconnecfl tion-18 and formedavith an operating handle" i 10 controls the admittance .ofthe fiuid, under pressure frointhe sourcei.of,,supply to, V

Whistle. A pinion 11 is mounted on the solid trunnion 5 and said pinioncooperates. With a'85 rack '12 carried by, theuppenend of an arm 12 pivoted, as at l3,at itsilovveriend'toone: of the side frame membensl A" li lgrlt i's; pivotally connected; at one "end. tofthe 12 and-sisformed;on its opposite, end .vvith ,19 0 an elongated openingl in vvhich is' adapt; ed to slide, a headed crank f pinl l iprojecting OUtW'HIIidlY- IEIOIH ,theiace. of a disk 15: carriedby a shaft 15, rotatably mountedin a bearings. 16 in the side fraine members, The inner face of the, disk-L15 :cai riesa gear- 17 Which; interme shes with alpinio'n 18 carried at one end of the, dni-ve .shaft'j'f19 ourn'a lled in bearings j 2Q in thelside'jfraine n embjers, and; the drive shaft ,carries, on, its oppositefloo a r which ntrm 'she's. with j P gear 2 pfifii sd-ea hfi diifiifli b the itllOWiEIQlIl anysuitahlesourcefofpovver." The, peripheral edge of the disk flo is proi vided Witha raised or camipor'tion 23 and pin 27 at the end of an arrow, the same operates in the following manner :The rotationof the disk 15 00a; point where the raised or rea'wardly and causes the valve 9 to be opened, permitting a blast to be issued from the whistle 7. The blast of the whistle will be directed by the deflector G in. one direction and will continue in that direction until such time as the pin let? completes its idle movement in the slot 1% and contacts with the forwardte'nd thereof. As the pin i4? contacts with the forward end of the slot 14, it will cause the link- 14: to be forced forwardly and raised at its slotted end, action operatin-g the rack 12 which will cause the deflector 6-toswing upwardly on its horizontal axis, and as the same passesover its center of rotation, it will fall gravity in the opposite direction; after the deflector has been operated, as above described, the rotation of the disk 15 will cause the raisedor cam portion 23 to complete its movement relative totne pin 24 and permit the spring'to closetlie valve. The continued rotation of the disk 1% will cause the pin 14 1 to contact with the rear end ofthe" slot 14f and cause the deflector" to be oscillated to the position in full lines the drawings, at whi'c htime the above stated: cycle of operation will again take place.

By employing the device as above described, on vessels with the definitely arranged standard that the operation is to be from bow to stern, it will be apparent that the operators on one vessel hearing first a volume of sound which is gradually reduced, owing to being projected in an opposite direction, they will know that a vessel is approaching, and if there is heard first a volume of sound which is, gradually increased, owing to being projected in a direction toward them, they wlll know; that a vessel is receding from them; the difference in the volume of sound being the means whereby the relative direction of travel of the respective vessels is ascertained.

It is to be understood that the present invention may be employed at light houses and in place of the audible signal buoys now in use in form of buoys, and when so em-- p oyed may be arranged in a y stated manarm 28 secured to the shaft, and secured at one end to this" cam portion 28 contacts with the pin 24, forces the same Y Shortly her known to mariners, to project the sonnd parallel to the shore line or in the direc tion of the channelt its be apparent that the soundirt "oera'tion during but one moventif of the deiio tor and remains silent during, the return movement thereof, and the uni form variatioir sf volume of sound will warn vessels of the direction of movement of each other.

, Having thus describedmy' invention what 1 claim as new and desire to protect by Letters Patent is 7 L- A signal comprising an intermittently operated movable sound deflector, a sounde ingi device associated therewith, and means:
